Answer:
Double-stranded RNA (dsRNA) are defined as the RNA having two complementary strands, same as DNA in all cells, in the replacement of thymine by uracil.
Double-stranded RNA derived from an intron are able to induce RNA interference and found to encode microRNAs (miRNAs), which are responsible for gene silencing mediated by RNA through RNA interference (RNAi) pathways.
miRNAs, which are small single-stranded regulatory RNAs that interferes with intracellular mRNAs (messenger RNAs) containing either complete or partial complementarity, are used to design new cancer therapies against polymorphism and viral mutation.
